Error message when I insert a global table into the dashboard

Hi @jordan.johnson

In my model when I insert a global table into a dashboard appears this error:

exception: FlexScript exception: Invalid down cast. Object is not an instance of the target type. at MODEL:/Tools/Statistics/Table of Values>variables/numseries exception: FlexScript

exception: Invalid down cast. Object is not an instance of the target type. at MODEL:/Tools/Statistics/Table of Values>variables/numcategories

Could you help me with this?

Thanks a lot.

Hi all,

I get the same exceptions if I try to add a global variable to a dashboard. Is there a solution for this, too?

I was able to apply the table presets (on the data tab, choose Apply Preset->Table Values), which fixed the issue.

Hi Lulú,

I assume that this is an oversight that will be fixed in a future release, right guys? :-)

For the time being, you can fix this issue by going to the Data tab of your chart, clicking the Code Editor / Script button for each of the fields and changing the first line from

treenode current = param(1);

to

Object current = param(1);

in all 5 fields (# Series, Series Title, # Categories, Category Title and Data Point Value).

Alternatively, you can use a Table control on the dashboard to display the table. This will also make it easier to copy/paste; downside is that the table will be editable by the user (suggestion for the developers: add an option to make the control read-only!).
